Randomized Controlled TrialA randomized controlled trial of the effect of preoperative dexmedetomidine on the half maximal effective concentration of propofol for successful i-gel insertion without muscle relaxants.
Dexmedetomidine is a useful anesthetic adjuvant for general anesthesia. We determined whether preoperative dexmedetomidine administration could reduce the half maximal effective concentration (EC50) of propofol for successful i-gel insertion without muscle relaxants. ⋯ Preoperative dexmedetomidine reduced the EC50 of propofol for successful i-gel insertion without muscle relaxants.

Feasibility, reliability, and validity of the Japanese version of the Postoperative Quality of Recovery Scale: a first pilot study.
The Postoperative Quality of Recovery Scale (PQRS) is a multi-domain tracking scale to assess recovery after surgery. The PQRS is used in seven countries and five languages; however, the Japanese version of the PQRS (PQRSj) has not been established. We therefore translated the PQRS into Japanese, and examined the feasibility, reliability and validity of the PQRSj. ⋯ A relationship was shown between cognitive domain and MMSE at baseline (r = 0.65, P < 0.01); however, no relationship was found between the other domains and the MMSE and QoR-40 J. Ceiling effects were observed in 78% of the questions. These results indicate that the PQRSj can be used to assess recovery after surgery, although it may be better to revise some of the questions to improve the validity of the PQRSj.

Perioperative management of carinal pneumonectomy: a retrospective review of 13 patients.
Carinal pneumonectomy is a challenging procedure because of the difficulties in surgical technique, intraoperative airway management, and postoperative respiratory and anastomotic complications. However, information regarding the anesthetic and intraoperative respiratory management of this procedure is scarce. This report describes our routine anesthetic and respiratory management strategy in patients undergoing carinal pneumonectomy. ⋯ No patient developed post-thoracotomy acute lung injury or required postoperative reintubation despite poor preoperative respiratory function. The 30-day mortality rate was 0%. Our airway management protocol for carinal pneumonectomy enables positive surgical outcomes.

Concomitant administration of nitrous oxide and remifentanil reduces oral tissue blood flow without decreasing blood pressure during sevoflurane anesthesia in rabbits.
To determine whether continuous administration of nitrous oxide and remifentanil—either alone or together—alters blood flow in oral tissues during sevoflurane anesthesia. ⋯ Our findings suggest that concomitant administration of nitrous oxide and remifentanil reduces blood flow in oral tissues without decreasing blood pressure during sevoflurane anesthesia in rabbits.
